We currently feed him "meals" of 1/5 can of Friskies every six hours. I've also been giving him snacks of 1/2 slice of deli-style turkey when I check his BG throughout the day.
We're planning to set up a feeder to give him a snack at PM +8 or + 9 as Jill suggested on Friday. We will check his BG at the time we would normally check it pre-shot, and feed him then as usual. I'll then check him at AM+2-3. My vet said anything between 100 and 200 is good, but I notice, as Julie says, that this site seems to prefer low 100s, so I guess that's what we're trying for. We had intended all along to keep testing him at what would have been AMPS and PMPS times. I'll post tomorrow morning after the +2 BG check. Thanks, all of you!
